The oldest date concerning the primitive work takes us to the
year 1445. The current church, with three naves, belongs to a late Romanesque, from the last quarter of the
12th century, where we can highlight the three fold semi-circular apse. Over the transept rises a tower built in brick, work carried out between 1710 and 1718. Two façades provide access to the building. The one in the side of the Epistle is very simple. The Gospel façade is the gem of this building and also of the late Spanish Romanesque of the 12th century.
It appears as a large ensemble, formed by five columns on each side, holding historiated capitals, above which, it runs a cornice on which stand archivolts, flanked outside by frame decorated with bestiary and allegories of vices, welcoming a tympanum with Christ in Majesty.
Inside, the Church has
three covered naves, on both sides covered with ribbed vault and the main, starry. It is remarkable the altarpiece dedicated to Santa Elena from 1406, the main altarpiece, a Baroque work carried out from 1735 to 1745 by
Jose Velaz de Lerín. Another one is dedicated to San Crispín and Crispiano , from 1602.
